CVE-2024-53080 Information

Description

In the Linux kernel the following vulnerability has been resolved:

drm/panthor: Lock XArray when getting entries for the VM

Similar to commit cac075706f29 (\drm/panthor: Fix race when converting group handle to group object) we need to use the XArray’s internal locking when retrieving a vm pointer from there.

v2: Removed part of the patch that was trying to protect fetching the heap pointer from XArray as that operation is protected by the @pool->lock.
